Sanjay Das

A
Software Engineer / Architect / Team-lead with experience in
Start-ups as well as Fortune-100 companies.

I
have architected / built horizontally scalable back-ends atop NoSQL
DBs, Big-data platforms, distributed RESTful API services. I have
hired / managed small-to medium size teams. I have proven ability to
jump into new projects and learn new technologies quickly. My passion
lies in building great products while enabling others to perform
their roles more effectively.

I
am particularly interested in piecing together popular open source
components and add proprietary technologies that address various
elements of the streaming pipeline (move, refine, store, analyze,
visualize, reprocess) for smart cities, agriculture and health care.

Data Services Company - Designed and built a new generation of Big Data platform to ingest and process massive amounts of data (via event-driven Microservices) both in batch and real time. (Java 8, Spark, NoSQL, Kafka, Avro, Git, Docker, Mesos and AWS)

Architected and Developed an on-line Stock Trading and cloud
based Algo Trading System. Notable achievement - Each trader
can spawn off an Amazon EC2 container with private access to Market
Data Cloud, Virtual Exchange and suite of Algorithms.

Consultant to an Investment Bank to implement a Credit
Derivative front office solution. Gathered business requirements and
implemented the requirements. Followed up with the users to test the
implementation and achieved sign-off towards go-live. (Java,
Tibco)

Consultant to a Hedge-fund to develop the front-end for a
trading platform based on a generic security model to support daily
trading and hedging activities for both front/middle office handling
a wide range of products. Mentored & handed over to Junior
Staff. (Java, Flex)

Developed Vostock
- a web-based continuous Auction System for Secondary stock
offerings.

The customer-facing web-site entertained thousands of
persistent (via applets) and HTML clients to participate in a live
auction. The back-end was entirely developed in Java on NT platform
and deployed on a Unix platform. Interfaced the Auction System with
US Clearing Corp’s Order Execution System & ADP’s
BPS Advantage. I was responsible for technical design decisions,
scalability, deployment, stress testing, coordination with outside
consultants and every other conceivable server-side technical issue.
(Java, JSP, Weblogic, Websphere, DB2)

Hired to architect next generation
distribute real-time trade reporting system from multiple databases
and setup an infrastructure for future Web-Based projects..

My achievements are: Came up with a basic underlying
design that is highly scalable & portable. It can scale to
multiple Web-Servers, multiple Application Servers and access
multiple Data-Bases. Business objects running in Application servers
can be interfaced with both web & non-web clients. All servers
can be run on either NT or Solaris platforms. (Java, Weblogic,
Informix).
